After being in print for twenty years, the Chronological Encyclopedia of Discoveries in Space, covering everything that was learned on every single space mission in the 20th century, has finally gone out of print.

"Useful to space buffs and generalists, comprehensive but readable, Bob Zimmerman's Encyclopedia belongs front and center on everyone's bookshelf." -- Mike Collins, Apollo 11 astronaut
"The Chronological Encylopedia of Discoveries in Space is no passionless compendium of information. Robert Zimmerman's fact-filled reports, which cover virtually every spacecraft or probe to have ventured into the heavens, relate the scientific and technical adventure of space exploration enthusiastically and with authority." -- American Scientist
The Chinese astronauts have undocked from the Tiengong-1 space station and will return to Earth tomorrow.
Following a separation from the Tiangong-1 at 7:05 a.m. Beijing Time, the manned Shenzhou-10 moved back to a point from where the spacecraft changed its orbit and flew around the target module. Under the command of ground-based professionals, Shenzhou-10 adjusted its flight gesture at a point behind Tiangong-1, and approached and rendezvoused with the target module.
The fly-around and rendezvous was apparently controlled by ground controllers, not the astronauts on board.
